So, i'm sitting here trying to determine which muffler of these three would have the best flow rate.
http://www.mandrelexhaustsystems.com...EXHAUST/Detail
The sound of each one is no concern to me. The only thing i'm looking for is which one of these three are going to flow the best.

From left to right:




Magnaflow Standard 5x8 Inch Body
Magnaflow Increased Airflow 6 Inch Body
Borla Standard 5 Inch Body


They're also all the same price, so that doesn't factor in at all.
Anyone with more muffler experience is more than welcome to chime in.

 

I have the borla and love it!

 

Awesome! . . . . . but really doesn't answer my question.

 

Blow into each of them and see how much more air comes out

 

Less than my turbo will push through the motor.

 

they probobly all flow the same. if anythign the straight through magnaflow is best. but I would go borla or something for flow and sound

 

The borla flows straight through too. It's sounds sick as he'll IMO and it's not crazy Loud like alot of exhausts are. Hope that helps more lol. I got excited haha

 

thats a very cheap exhaust.... damn

 

I've always been a fan of the borla sound...especially on small displacement engines

 

im probobly going to same catback eventually with the borla muffler. Looks like an amazing deal

 

its aluminumized its going to rust ...

 

You know what aluminum is right???

And not to be a dick but put your car on a lift and
look at your stock exhaust pipe. It's the same

 

ALUMINIZED steel will rust. it not aluminum if thats what your hinting at nick name Canada steel T304 its heavier than US T304 steel which wont rust

stock duh, but why would you want to buy something that going to rust out....note i dont have factory exhaust mine custom and i didnt think your a dick....

 

Well only time will tell? I live in the desert so somthing tells me I'm good to go lol

 

i have the standard body magnaflow and love it u can see straight through the muffler so yeah

 

air and water both affect the metal, but you should be better off then most

 

And as far as paying for something that might rust I think ppl would do it cause it's so damn cheap and the performance gains from the 3" are amazing for the price.

 

meh you kinda got a point there....i guess i just made mine to last its also a 3inch under axel yes yes i know you going to say wtf....i have now knocking or clearance issues, im also lowered. i just made it to last

 

i was looking into these exhausts as well, and there dp's

 

it depends on where you live if aluminized is ok.. however.. they also sell the same thing in stainless i'd go with borla for sound and flow though

 

JDM what!!!!??? lol who makes under axle?

 

nice exaust lol

 

made it my self, jdm my ass buddy. theres like no restriction. its custom... dont knock it til you try it...my goal was to have something different which i think i did.







this is a lfn thread i know this is on my lsj my lnf will be getting one soon as i have the time

 

Wow... There really isn't any restriction in that exhaust, but around here 2" of ground clearance wouldn't cut it.. you must have better roads around where you live.

To the original poster - the Magnaflow Increased Airflow 6 Inch Body probably has the highest air flow. That is also the muffler that Hahn uses on his exhaust, I believe.

 

better roads my ass u just gotta pay attention to the roads....

and derek I never new they made aluminized t304 steel.

aluminized steel and t304 are 2 completely different types of steel t304 is stainless with low iron content and aluminized is the bottom of the barrel steel
